Bridges and crowns are fixed prosthetic devices that are cemented onto existing teeth or implants by a dentist. Different types of Crowns being offered in our Clinic are Zirconia Crowns, Metal & Metal Facing Ceramic Dental Crown, Porcelain-fused-to-metal / Metal Ceramic, Implant Supported crown.
Crowns are used most commonly to entirely cover or "cap" a damaged tooth or cover an implant. Bridges are commonly used to cover a space if you’re missing one or more teeth. They are cemented to natural teeth or implants surrounding the space where the tooth once stood.
A dental crown may be needed in the following situations:
These are used for restoring all teeth, and are popular for their ability to blend with your natural tooth colour. The crown is made of a porcelain-based material.
This crown provides a stronger bond than regular porcelain because it is connected to a metal structure. It's also extremely durable.
This crown is made of gold. In addition to providing a strong bond to the tooth, it doesn't fracture, nor does it wear away the tooth itself.
This crown is made up of non-noble metals that are highly resistant to corrosion, and make for a very strong crown. It also requires the least amount of healthy tooth to be removed prior to fitting.
Before either a crown or a bridge can be made, the tooth (or teeth) must be reduced in size so that the crown or bridge will fit over it properly. After reducing the tooth/teeth, your dentist will take an impression to provide an exact mould for the crown or bridge. If porcelain is to be used, your dentist will determine the correct shade for the crown or bridge to match the colour of your existing teeth. Using this impression, a dental lab then makes your crown or bridge, in the material your dentist specifies. A temporary crown or bridge will be put in place to cover the prepared tooth while the permanent crown or bridge is being made. When the permanent crown or bridge is ready, the temporary crown or bridge is removed, and the new crown or bridge is cemented over your prepared tooth or teeth. All the materials mentioned above can be used to make the bridges
